There are new charges a powerful tool used by the U.S. government to surveil foreign suspects may have been used against the Donald Trump campaign, based on findings now shown to members of the House Judiciary Committee.

Iowa Rep. Steve King tweeted what he saw in the memo is “worse than Watergate.” He and others are now calling for it to be made public.

When asked what is in the memo, Rep. Ron DeSantis (R-FL) said “I can just tell you that it substantiated a lot of concerns that myself and other members have had.”

DeSantis said those concerns include political motivations being behind granting a request under the Foreign Intelligence Surveillance Act (FISA), possibly using the infamous Christopher Steele dossier as evidence.

“The question is, did you take that opposition research, unverified and did you use that to get a surveillance at the FISA court against Trump associates? DeSantis asked, adding those questions need answers.

Julian Sanchez, with the libertarian Cato Institute, said in an interview right now is pure speculation.

“The question becomes is this something based on genuine evidence they've seen of wrongdoing or is it speculation about what they think might have happened?” he said. “If it turns out that this opposition research document was the only basis for a wiretap application, that would certainly be cause for concern. But you would hope that the FBI and the FISA court would not be willing to wiretap an American citizen based only on that without corroboration, he added.

The memo, put together by Republican staffers with the House Intelligence Committee, seems to suggest there were political motivations at play from the Department of Justice and the FBI. Critics however point out they’re simply trying to undermine Special Counsel Robert Mueller’s investigation as it continues to connect more dots between Russia and the Trump campaign.
